You don't differentiate using L'Hospital's Rule, you differentiate the top and the bottom because that's what you need to do to USE L'Hospital's Rule. Anyway
Hello, I am trying to diffferentiate using l'Hopital's rule:
(e^(5+h)-e^5) / (h)
to find the limit of h tending towards zero.
I differentiate the numerator and denominator to get:
(e^(5+h) - e^5) / (1)
but I think I should be getting (e^(5+h)) / (1)
Can someone please tell me how the second e^5 is done away with ?
